SEWING MACHINE GUIDE Fii ed May 22, 1953 2 Sheets-Sheet 2 J'YC'K POLJKOFF GEORGE Lam/60 INVENTORS ATTORN EY Patented Apr. 10, 1934 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to a sewing machine guide and it has as one of its objects the provision of a guide which may be moved from a I position below the throat plate of the sewing machine to a position above the same and vice versa, the guide being preferably held below the plate, means being provided to move the same to a posi tion above the plate, said means being preferably adapted to be so moved by the operators leg.

The invention will be fully and comprehensively understood from a consideration of the following detailed description when read in connection with the accompanying drawings which form part of the application, with the understanding, however, that the improvement is capable of extended application and is not confined to the exact showing of the drawings nor to the precise construction described and, therefore, such changes and modifications may be made therein as do not afiect the spirit of the invention nor exceed the scope thereof as expressed in the appended claims.

In the drawings:

Fig. 1 is a bottom plan view of the guide of our invention shown attached to the lower face of the base of a sewing machine.

Fig. 2 is a section taken on line 2-2 of Fig. 1 and shows fragmentarily part of the sewing machine above the base.

Fig. 3 shows the guide in guiding position, as distinguished from its normal and retracted position, as indicated in Figs. 1 and 2; and

Fig. 4 is a plan view of a blank for a sandal.

Referring to the drawings for a more detailed description thereof, the numeral .5 indicates the base plate of the sewing machine. Flush with said base plate is a throat plate 6 thru the apertures 7 of whichthe needle 8 is adapted to move reciprocatingly. Said throat plate is provided 0 with an aperture 9, thru which is adapted to move a guide 10 having a resilient shank 11. The

shank is attached to an end of a rod or bar 12 which is held in. retracted position by a coiled spring 13, one end of said spring being attached to a bracket 14 secured to the lower face of the base plate. The coil 13 holds the guide 10 below the upper face of the throat plate and to one side of the opening 9. When it is desired to move the guide 10 to a position above the throat plate,

as illustrated in Fig. 3, the operator moves his knee against a lever 16, which is pivotally mounted at 17 on a bracket 18. Movement of said lever to the left is effective to move the bar 12 to the left and to also move the guide to the left 5 and permit it to be moved by the spring action of its shank 11 thru the aperture 9 to the position above the throat plate, as shown in Fig. 3. Inasmuch as the lever 16 is pivotally connected intermediate its ends to a strip 20 which is pivotally connected at its upper end to the bar 12, as indicated by the numeral 21, it will be noted from Figs. 2 and 3 that the lower face of the throat plate 6 is bevelled adjacent the aperture 9 so that the guide rests on the bevelled face when in retracted position and is enabled thereby to be easily moved into the aperture 9. With the guide in position above the throat plate, as shown in Fig. 3, it functions as a stitching guide, being adjacent the needle 8 when the latter is passing thru the throat plate.

The movable guide of our invention is valuable in that at one time work must be done with the machine which does not require a guide or on which a guide could not be used, while at other times work must be done which requires the use of a guide. It will be readily appreciated that the guide of our invention may be readily moved from guiding to retracted position and vice versa, so that it is not necessary to stop the machine in order to put a guide in place or to remove it, which has been heretofore necessary. Our invention is valuable in stitching, for example, the sandal blank shown in Fig. 4, the guide being used where the blank itself is stitched, but not being used when the straps 25 are stitched to the blank.

What is claimed is:

1. The combination of the throat plate of a sewing machine with a guide movable from below the throat plate to a position above the same and vice versa thru an aperture formed therein, and spring means for normally holding said guide below said plate, said guide including a resilient shank.

2. The combination of the throat plate of a sewing machine with a guide movable from below the throat plate to a position above the same and vice versa thru an aperture formed therein, spring means for normally holding said guide below said plate, said guide including a resilient shank, and means adapted to be actuated by the leg of the operator for moving said guide to a position above the plate.
